Title: Control device for engine rpm
Inventor: SATO MASAMI
IPC: F02D41/14
Filed: 1987-01-23
Abstract: PURPOSE:To prevent an engine from panting or stalling by constituting a controller for operating a mixture adjuster so that a target rpm is changed gradually, when the output of an engine condition detector changes, to a final target rpm. CONSTITUTION:During operation of an engine, the amount of mixture is adjusted to stabilize the engine rpm by manipulating a mixture amount adjuster 3 to produce a specified target rpm according to the engine condition by means of a controller 1 for inputting an output from an engine condition detector 2 for detecting the engine condition. In such a control device, the controller 1 is constituted such that, when the output of the engine condition detector 2 changes and the target rpm changes from R0 to R1, the target rpm can be changed gradually from R0 to R1 over a specified period of time. With this constitution, the engine can be prevented from panting or stalling.

Title: Total testing device for motor
Inventor: MATSUMOTO SHIGERU
IPC: G01R31/34
Filed: 1980-02-09
Abstract: PURPOSE:To improve precision by measuring effective values of a voltage and current accurately by converting the analog signal that corresponds to a voltage or current value into a digital signal and then by processing it by providing Fourier transforming, squaring-summing arithmetic and square-root arithmetic circuits. CONSTITUTION:An analog signal of a voltage is amplified by insulating amplifier 3a and then inputted to low-pass filter 3b and clock generating circuit 3. The analog signal is inputted to A/D converter 3d, and a clock signal from clock generating circuit 3c, on the other hand, is inputted to A/D converter 3d as a sampling signal and then converted into a digital signal. This digital signal is Fourier-transformed by Fourier transforming circuit 3e and outputted in the form of a complex spectrum consisting of a real part and imaginary part. This output of Fourier transforming circuit 3e is inputted to squaring-summing arithmetic circuit 3f and then square-root arithmetic circuit 3g to calculate the effective value of the input voltage. This constitution can measure accurately the effective value of a current as well as a voltage in any waveform, so that the precision of data can be improved.

Filed: 1979-02-14
Abstract: PURPOSE: To achieve higher performance by specifying the applied voltage and circuit constant of a high-voltage switching circuit.  
     CONSTITUTION: The voltage power source E which applies the applied voltage of a high-voltage switching circuit 12 which switch later with a delay and the inductor L 2 , resistance R 2  and capacitor C 2  inserted in the circuit 12 are made respectively variable, and the number of series-connected avalanche transistors Q 1 WQ 13  is made slightly less than the number of the avalanche transistors Q 1 WQ 15  of the high- voltage switching circuit 11 to be switched in precedence. As a result of this, the waveforms of the dropping of the high-voltage pulses applied with a delay to the right electrode terminal of a Pockels cell Cp, including the amplitude of the waveforms at the dropping of the high-voltage pulses having been previously applied to the left electrode terminal become nearly the same, thus the leak rate of the light pulses after the chopping of the light pulses may be made sufficiently small.

IPC: H01L31/10
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To obtain a high-accuracy and wide-ranging light monitoring output by using different amplifiers of a plurality of gains. SOLUTION: An analog switch 7 selects the output of a D/A conversion circuit 9 for reference voltage generation use by a microcontroller 12. A voltage, which acts as the boundary line of a selection of the output of an amplifier 10C of a gain 16 and the output of an amplifier 10D of a gain 64, is generated by the circuit 9, and a ratio K3 (K3=V4/V3) of a value V3 of the output to a value V4 of the output subsequent to the A/D conversion of an output amplified by 16 times the voltage and an output amplified by 64 times the voltage are found. First, the obtained numerical value is read in unmagnified mode.  When the A/D conversion values of the read numerical value are between 16 and 63, a rereadout of the read numerical value is executed in a 16-fold mode (An analog switch 8 selects the four-fold amplifier 10C.) and the reread value is multiplied by K3, to set the obtained value as the value of an input light level of a light output monitoring circuit.
